WATER-HEATER.

SPECIFICATIONfOrming part of Letters Patent NO. 758,347, dated April 26, 1904.

Application filed June 26, 1901.

To all whmn it may concern:

Be it known that I, SAMUEL BERNSTEIN, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in ater-Heaters, of which the following is a specification.

My invention relates to water-heaters, and more particularly to that class of apparatus known in the art as instantaneous waterheaters, and having as an object-to provide means for readily heating water for the bath or Much diificulty has been experienced with water-heaters of this type on account of the fact that the watery vapor formed by the combustion of the fuel condenses on the heating-surfaces in such quantities as to form an objectionable drip, for the disposal of which special drain connections ordinarily have to be provided. This water of condensation, moreover, if allowed to collect at any point in the heater soon forms a slimy substance which renders the apparatus filthy and unfit for use until it is taken apart and cleaned.

My invention has for an object toprovide an apparatus in which the drip referred to is automatically disposed of 7 without the necessity of any special drainconnections.

Other objects of my invention are to so construct and arrange the heating-surfaces that the apparatus shall not become foul due to the standing therein of the water of condensation; also, to provide a construction which is simple and inexpensive and which may be quickly and easily assembled and-taken apart to be cleaned or inspected and to otherwise improve heaters of the class referred to and render the same more practical and convenient than they have proven to be as heretofore constructed.- With these and other objects in view my invention consists in the novel parts, improve meuts, and combinations herein shown and described. The accompanying drawings, which are re ferred to herein and form a part hereof, illustrate one embodiment of my invention and serve, in connection with the description herein, to explain the principles of my invention 'cordance with my invention.

Serial No. 66,045. (No model.)

and the best mode in which I havecontemplated applying those principles.

Referring to the drawings, Figure l is a side elevation of an apparatus constructed in ac- Fig. 2 is a vertical central section of the same. Fig. 3 is a vertical central section of the base of the apparatus, the section being taken in a plane at right angles to that of the section in Fig. 2. Figs. 4 and 5 are respectively a top and an inverted plan view of the base.

Like reference-numbers refer to like parts throughout the several views.

My improvements have special reference to that type of instantaneous water-heaters in which the water is distributed in one or more thin expansive streams over a heated surface or surfaces and is collected and conveyed out of the heater as rapidly as it passes therethro ugh, although my invention as to some of its features is not limited to this particular type of heater.

Referring to the drawings in detail, l indicates the casing which contains the heatingsurfaces and water-distributing devices which constitute the upper part of the apparatus, and 2 indicates the base upon which the upper part of the apparatus is mounted. In accordance with the construction shown the base 2 consists of a unitary casting, having an inner hollow portion 3, constructed to form a burner for a mixture of air and gas or other fuel, and

an outer flange portion 4, constructed to receive and support the casing 1 of'the heater.

The hollow portion 3 may be provided with any suitable means to admit the fuel and'the air necessary to support the combustion to the combustion-chamber. As shown, the hollow portion 3 is annular in form and is provided on its upper surface with a multiplicity of perforations 5 to admit the fuel mixture to the combustion-chamber, the air beingsupplied through the central opening 6; The fuel mixture may be supplied to the hollow portion 8 in any suitable way, as by the combining-tube 7, into which the gas is discharged through a nozzle 8. The flange portion 4: is joined to the inner portion 3, preferably at some point below the top thereof, and is providedat or near its periphery with an upturned lip 9,

within which the lower end of the casing 1 is fitted.

The flange 4: and lip 9, together with the outer wall of the hollow portion 3, form a trough-like receptacle into which the water of condensation is drained, and as this receptacle is directly connected With the burner it is kept at such a high temperature by the heat conducted through the metal from the burner that the water of condensation is evaporated as soon as it comes in contact with the metal. For the purpose of conveying away the vapor formed by the evaporation ofthe water of condensation and supplying the air necessary to make the combustion at the outer portion of the burner complete a plurality of openings are preferably formed in the flange ibetween the lip 9 and the hollow portion 3, and to preventthe escape of the water of condensation through these openings they are providedwith upturned lips, as shown.

The casing 1 is preferably loosely fitted within the lip 9, so that the upper part of the heater can be readily removed from the base to be cleaned or inspected. The base,2 is preferably supported by a pair of wall-brackets 11, and to this end it is provided withsets of lugs 12 and 13, adapted to rest upon and be secured to the said brackets. For the purpose of readily lighting the burner it may be provided at its outer edge with a short extension 14, having a row of small lead-openings, as shown, the casing l being provided with a suitable opening 15 to accommodate the extension 11 and the flame formed thereon.

In accordance with my present improvements the heating-surfaces are constructed and arranged substantially as follows: An upwardly-tapering Wall 16 is permanently secured at its lower edge to the casing 1 a short distance above the base 2, and an upwardlyfiaring wall 17 is mounted within the casing 1, with its lower end overlapping the upper end of the upwardly-tapering wall 16. The wall 17 is provided at an intermediate portion with two sets of openings 18 and 19. A transverse partition 20 is mounted within the upwardlyflaring wall 17 between the sets of openings therein, so that the products of combustion will be caused to take a zigzag course. The partition 20 is preferably somewhat dished or crowned upwardly and provided With a crimped or serrated edge, so that any water falling thereon will run down to the inner surface of the wall 17 and be evenly distributed thereon. An upwardly-tapering centrallyapertured partition 21 is located within the casing 1, with its outer edge overlapping the top of the wall 17 and resting in contact with the inner surface of the casing 1. The partition 21 is provided with a perforated channel or depression 22 adjacent to the inner surface of the wall 17, and the outer edge.of the partition is serrated or crimped, so as to form a plurality of openings between it and the inner surface of casing 1. It will be seen that any water falling on the upper surface of the partition 21 will be distributed on the inner surface of both the wall 17 and the casing 1. For the purpose of supplying water to the upper surfaces of the partitions 20 and- 21 a pipe 23 is mounted in the casing 1, said pipe being removably connected at its lower end to the supply-pipe 24:, as by means of a union 25. A laterally-extending branch pipe 26 is threaded to the upper end of the pipe 23 and is provided at its inner end with a spray-nozzle or rose 27, which is preferably provided with two sets of perforations 28 and 29, which are respectivelyarranged to supply water to the partitions 20 and 21. It will be seen from this construction that every part of the surface in the heater upon which water is deposited, either by the water-distributing devices or by the condensation of the vapors in the apparatus, is inclined downwardly, so that the water will be drained either into the collecting-chamber formed between the wall 16 and the casing 1 or into the evaporating-receptacle formed by the flange 4t, and that every portion of the heating-surfaces which are not continually Washed by the streams of water formed by the distributing devices are arranged directly in the path of the heated products of combustion. .lt Will thus be seen that no moisture can collect and stand in any part of the apparatus so as to render the same filthy.

In order that the apparatus may be readily taken apart to be cleaned or inspected, the pipe 23 is preferably carried above the top of the casing 2, so that the branch 26 can be swung outwardly from its normal position over the partition 21, and the partition 21 and the wall 17 and preferably, also, the partition 20 are loosely mounted in position, so that they can be readily removed and replaced. The upper end of the apparatus is preferably inclosed by a cover 30, having an outlet-passage 31 for the waste gases, and a dischargespout 32 is provided to convey away the heated water as rapidly as it collects at the lower end of the casing.

It will be seen that by simply disconnecting the coupling the upper part of the heater may be removed from the base and so taken apart that every portion of it can be readily .and thoroughly cleaned. It will also be seen that the construction is simple and inexpensive and not apt to get out of order.

My invention in its broader aspects is not limited to the precise construction shown nor to the precise construction by which it may be carried into effect, as many changes may be made in such construction without departing from the main principles of my invention and without sacrificing its chief advantages.
